Embodiments of systems and methods for signaling chroma information for a picture in a compressed video stream are provided. One system embodiment, among others, comprises a memory with logic, and a processor configured with the logic to provide a compressed video stream that includes a picture having chroma samples and luma samples, and provide in the compressed video stream a flag for signaling information corresponding to the location of the chroma samples in relation to the luma samples in the picture, wherein a first defined flag value indicates default locations of the chroma samples in relation to the luma samples in the picture, wherein a second defined flag value indicates a presence in the compressed video stream of auxiliary chroma information corresponding to relative locations of the chroma samples to the luma samples in the picture, and wherein the number of chroma samples in the picture implied by the first defined flag value is equal to the number of chroma samples in the picture implied by the second defined flag value. Other embodiments for signaling chroma information for a picture in a compressed video stream are included herein. |
